ISSN 0028-0771 August 2012 Volume 137 Number 1080 Editorial A year ago we presented an issue of The Naturalist containing several articles about natural history around Leeds. With this issue we have articles relating to the Scarborough district. The editors are grateful to the members of the Scarborough Field Naturalists' Society and the Yorkshire Naturalists' Union and others for contributing these articles. We hope to produce an issue next year which contains a group of articles relating to another part of Yorkshire. If you are willing to co-ordinate such a series of articles then please get in touch with us. While the two issues so far have dealt with a city and a town, it is not necessary to cover such large areas every time. The wildlife of a village, a parish, a river valley or even an individual site could form the subject of such an issue. As with the Leeds and Scarborough ones, we welcome information on history, management and conservation issues as well as articles on particular groups or even individual species of animals and plants. You will see from this issue that articles can range from a single page to several pages. We are keen to encourage contributions from naturalists who may never have written articles for publication before and short notes on their experiences would be a gentle first step in sharing their knowledge with the rest of us. The 'Notice to Contributors' on the inside back cover applies to such articles. The themed issues benefit enormously from good photographs as, indeed, does every issue of The Naturalist. We cannot pay for using your photographs but the photographer is credited in each one. We are very grateful when members offer us the use of their work so please contact us if you have photographs which you would be willing to see in future issues. The Naturalist 137 (2012) 81 The Hazel Dormouse release project at Freeholders’ Wood in the Yorkshire Dales National Park I. White People's Trust for Endangered Species, 15 Cloisters House, 8 Battersea Park Road, London, SW8 4BG email: [email protected] I.R. Court Yorkshire Dales National Park Authority, Colvend, Hebden Road, Grassington, Skipton, North Yorkshire, BD23 5LB. email: [email protected] Abstract The Hazel Dormouse Muscardinus avellanarius has become extinct in Yorkshire over the past 100 years. There have been two previous attempts to establish a breeding population in the county which may have been successful. A third re-introduction was undertaken in Freeholders' Wood in 2008; this required a slight change in the management of the wood, an input from a variety of organisations and the help of a number of volunteers. To date the project appears to be successful with good dormouse numbers recorded and evidence that the species has at least dispersed throughout the woodland. Introduction In 1885 Rope identified a number of locations in Yorkshire at which the Hazel Dormouse had been recorded. Howes (1985) noted some more recent records from the 1950s and 1960s; and although there were a couple of records from 1979 and 1980, these were not substantiated (Oxford 1999). The next national survey on this species was not undertaken until 1993 when the first Great Nut Hunt provided very good evidence that dormice had become extinct in the county of Yorkshire during the preceding hundred years. The Hazel Dormouse was once widespread in woods throughout Britain but the Great Nut Hunt showed that, apart from populations in Cumbria and Northumberland, the Dormouse had been lost from Yorkshire and at least six other northern and midland English Counties. Further research work on the species showed that not only had the range reduced but also the population had diminished significantly over the past 100 years (Bright & Morris 1995, Sanderson 2001). The loss was chiefly thought to be due to the isolation of woods, changes in woodland management and both the loss and inappropriate management of hedgerows. The species is very sensitive to environmental factors and so the woodlands and scrub they inhabit needs to be well managed at both the local and landscape level. Due to the apparent decline of the Hazel Dormouse, the species was granted protection under the Wildlife and Countryside Act 1981 and this has been enhanced by the Conservation of Habitat and Species Regulations 2010. A national Biodiversity Action Plan (BAP) for dormice was instigated in 1995 to help conserve the species, aiming to “maintain, enhance and re-establish dormouse populations within their historic range”. To achieve this, the National Dormouse Monitoring Programme (NDMP) was set up to examine the national population trend of the Hazel Dormouse by the regular monitoring of a large number of sites where dormice are known to exist. This has shown that the dramatic population decline in the past 50 years finally appears to be slowing and over the past 20 years there has been an effort to return the Dormouse to some of the counties from which it has been lost or where its numbers are low. The species has been re-introduced to 17 sites in 11 counties since the first re-introduction took place in Cambridgeshire in 1993. Unfortunately the releases at three of these sites do not appear to have been successful, probably due to inappropriate or 82 The Naturalist 137 (2012) insufficient woodland management.

Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species. Fauna norvegica 32: 45-52. A total of 5 nudibranch species are reported from the Norwegian coast for the first time (Doridoxa ingolfiana, Goniodoris castanea, Onchidoris sparsa, Eubranchus rupium and Proctonotus mucro- niferus). In addition 10 species that can be considered rare in Norwegian waters are presented with new information (Lophodoris danielsseni, Onchidoris depressa, Palio nothus, Tritonia griegi, Tritonia lineata, Hero formosa, Janolus cristatus, Cumanotus beaumonti, Berghia norvegica and Calma glau- coides), in some cases with considerable changes to their distribution. These new results present an update to our previous extensive investigation of the nudibranch fauna of the Norwegian coast from 2005, which now totals 87 species. An increase in several new species to the Norwegian fauna and new records of rare species, some with considerable updates, in relatively few years results mainly from sampling effort and contributions by specialists on samples from poorly sampled areas. doi: 10.5324/fn.v31i0.1576.
